Vacuum Presure Impregnation (VPI) System

Vacuum Pressure Impregnation (VPI) system has been used in the high voltage motor and generator manufacturing and service industries for many years. It is the most effective process to-date for removing air, moisture and volatile from the winding prior to varnishing.

MES service workshop in Singapore has now equipped with a modern VPI system. Its process tank has a dimension of 2.5 metres diameter x 4.0 metres length, i.e. a volume of 20 cubic metres (700 cubic feet). The VPI system specially designed by the Epoxylite Corporation of USA. The process tank is capable to withstand a working pressure from full vacuum to 7 bars (or 100 psig). The use of Epoxylite #478 solventless resin in our VPI system allows us to obtain a completely filled 100% solid insulation structure and a smooth continuous coating on the external surfaces of the wound coils.

With this state-of-the-art VPI system, we are able to provide complete and void free impregnation for form-wound medium (2.3 - 5.0 KV) and high voltage (6.6 - 13.8 KV) stator, rotor and armature winding. The electrical insulation resistance, mechanical strength, coil rigidity, heat transfer characteristics and environmental resistance of the insulation system will all be greatly improved. The life expectancy of your motor and generator windings will be extended by at least 50% as compared to those winding gone through the usual dipping process or VPI using solvent-containing varnish. Our VPI process fully meets the specification set by IEC, BS and IEEE for sealed winding systems.

The VPI system with solventless epoxy resin is particular beneficial to motor and generator users in the heavy and hazardous environment industries such as offshore exploration, drilling and production, oil and gas refineries, petrochemical industries, pharmaceutical industry, power utilities, marine industries, pulp and paper mills, steel mills, cement mills and other sectors of industries.

In summary, the use of the Vacuum Pressure Impregnation System with solventless epoxy resin for stator and armature treatment yields several benefits :

  • Improved protection against harsh environmental conditions
  • Thermal conductivity for cooler operation of machines
  • Elimination of voids for improved voltage endurance
  • Greater mechanical strength through unit bonding

Using MES services will give you all these benefits. Please call MES - the only shop in this region equipped with this unique and modern facility.

Condition Monitoring - Predictive Maintenance Technique

Maintech Engineering & Supplies is the authorized reseller, with Rockwell Automation in Singapore, to provide condition monitoring solution such as vibration Measurement and Analysis. There are many specific problems that can cause a machine to exhibit excessive vibration. To locate the root cause of vibration, an analysis of the vibration is required.

Condition Monitoring, as part of a Condition-based Maintenance (CbM) program, gives you the critical information you need to optimize scheduling of downtime, labor and materials - so you can increase productivity while reducing costs.

Condition monitoring uses predictive maintenance technique, for identifying rotating machinery, needing maintenance attention before its performance gets to the point of product quality is affected or an unplanned shutdown occurs, that will resulted in downtime.

Predictive maintenance will provide maintenance and operations with intelligent information, that allows not only protect machinery from catastrophic failures, but also aids in planning production and maintenance activities.

We offer the following products, for your solutions:

1) Protection Systems : Allen-Bradley® XM® series of intelligent I/O modules
2) Portable Systems: Enpac® portable condition monitoring data collectors
3) Sensors & Accessories: 9000 series Accelerometers
4) RSMACC Enterprise Online
